Testing the Hypothesis Pt. 2

Summary of my 5 new interviews:

Instead of individually summarizing each interview I did, I thought it would be more efficient this time to collectively summarize all five of them in one explanation. 
I realized that the issue of paper straws not being sufficient straws applies to most people, but there are a few certain people, and mainly businesses, that may fall outside the boundary.  A few of the people I interviewed pointed out that some very environmentally-conscious people carry around their own metal or silicone straws.  These people would definitely fall outside of the boundary because they don't need an alternative to paper straws, they already purchased their own and carry it around with them.
Someone else also brought to my attention that certain restaurants across the country use metal straws that they wash and re-use for the drinks that they serve. Even though this is more work for them, it eliminates the need for a plastic or paper straw. Businesses that choose to do this also fall outside the boundary of needing a paper straw alternative, because they have their own measures being implemented and put in place in their own restaurants. 
Regarding the "what", my responses were more mixed. Some said that the need I identified for a better plastic straw alternative that isn't paper is a very specific need, and there is a wide audience that would want that kind of product. Some also said that this need could be kind of confusing, because at the end of the day... is there a need for a straw? Can't people just not use one?  To this, I counter that with drinks like smoothies, people almost always want a straw because they can be messier to drink. I do see the point though. 
Someone also said something that I thought was really interesting. There is a want/desire for a great straw alternative that is durable and good for the environment, but there is also a want/desire in some people to appear environmentally conscious. This sounded strange to me at first, but I completely understood after they explained more how it is a current "trend" to "go green" and join the fight against climate change and do things that are environmentally friendly. People would not just want the straws solely because they want a great straw option, but also because they want to feel like they are doing something positive for the environment and want to convey that to others. 
I overall gathered that even though there are people outside of the boundary who don't have a need for a great, new straw alternative that isn't made of paper, they still will experience this problem at least once.  The underlying cause is the same for both groups, because paper straws will work in the same faulty way for everyone that uses them. However, the outside boundary group may solve the problem themselves by buying their own straw or just choosing not to use one. 

Inside the boundary	Outside the boundary
Who is In: anyone that wants to use a straw NOT made of paper in their beverage at home or out at restaurants/cafes.	Who is Not: people and businesses who have purchased re-usable metal or silicon straws, so they don't use the paper straws that are provided to then when they're out. Also, people that just don't care and are OK with not using a straw.
The need: an environmentally-friendly straw that is made of a natural material that also won't disintegrate in liquid, and isn't too expensive.	What the Need Is Not: Not using a straw, or buying your own to carry around with you.
Why the Need Exists: plastic straws have become illegal because they hurt the environment. However, the alternative is not very functional as a straw and becomes limp/disintegrates in the drink, making it unusable before the drink is even done.	Alternative Explanations: Having a straw may not be a big deal at all for some people, they are totally fine with not using straws at all or actually think paper straws are OK if they drink their drink fast enough.
